Davirus Posted July 28, 2019 Share Posted July 28, 2019 Is there an alternative PMDrvr for 9700k CPUs? Link to comment Share on other sites More sharing options...

Isidore Isou Posted March 31, 2020 Share Posted March 31, 2020 Hello THANK YOU for this Kext. Very good performance and very low consumption in idle. I'm using it with Opencore, and it's the only way for me to have good performance and good speedsteps. On my machine, Opencore XCPM does not work very good, idle is fine but poor performance during load. This problem is solved with the use of this Kext. Some things: During load, Intel Power Gadget display a wrong information about Core Util., 50 instead of 100. Strange but minor problem. Is there anything I have to check to use it with Opencore? Don't want to create conflicts or hardware issues. Should I disable CPU SSDT or CPU Fake ID in Opencore? Link to comment Share on other sites More sharing options...
Isidore Isou Posted April 1, 2020 Share Posted April 1, 2020 I confirm that this patch works well on X99 / 5820k / 10.15.4 / Opencore 0.5.6. The only problem is that Intel Power Gadget display wrong information about the "CORE Utilization". The information on activity monitor are correct.

AslashA Posted August 21, 2020 Share Posted August 21, 2020 With the PMDrv.kex driver without mask as Haswell and quirk AppleXcpmExtraMsrs in OpenCore, I have only 4 p-states. And the highest of them is only 2900 MHz. With the PMDrv.kext driver, but with mask as Haswell and quirk AppleXcpmExtraMsrs, I already have 9 p-states. Moreover, the highest state is 3300 MHz. It is very important! Before (just with PMDrv): After (with PMDrv + mask and quirk): Is it possible to do something so that with the PMDrv.kext driver all states work without kernel patches? P.S. Only I did not understand one thing. Why does not the multithread rate increase with increasing single thread??? Link to comment Share on other sites More sharing options...
AslashA Posted October 27, 2020 Share Posted October 27, 2020 Does the driver work in macOS Big Sur? 1 Link to comment Share on other sites More sharing options...
AslashA Posted February 3, 2021 Share Posted February 3, 2021 I found that the boot stop, which is often called by the PMDrv.kext driver in bigsur, is identical to the stop that is observed if npci = 0x2000 is removed from bootargs, i.e. the loading stops at exactly the same place. How can this be related? 1 Link to comment Share on other sites More sharing options...
